Silver k eagle audio in mic works fine. Ets tones not working while board is installed in mic. Unmount board from mic and tones work fine at first I thought there was something wrong with the board so I took another board out of my other k eagle and it does exactly the same thing I’m thinking some kind of ground issue but I cannot figure it out. Any help would be greatly appreciated
 

Sure sounds like a crack in a foil trace or a failed solder connection. Might try flexing the pc board slightly while it's out of the mike. I suspect what causes the difference is mechanical in nature, and tightening the screws causes the board to flex just enough to cause the fault.
